HENRY FRIDAY, OF HOUSTON, TEXAS.

WlRE-STRETCHING DEVICE FOR FENCE-POSTS.

SPECEFICATIQN forming part. of Letters Patent No. 337,865, dated March 16, 1886.

Serial No. 185,281. (No model.)

.To all whom it may concern.-

Be it known that I, HENRY FRIDAY, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented a new and useful Improvement in lVire-Stretching Devices for Fence-Posts, of which the following is a specification, reference being had to the accompanying draw- 1ngs.

My invention has relation to improvements in fence-posts; and the novelty consists of the peculiar construction and combination ofparts, substantially as hereinafter fully set forth, and specifically pointed out in the claims.

My invention has for its objects to provide improved means for simultaneously stretching to an equal extent or degree the wires of a fence located on opposite sides of one of the posts, whereby the strain on the post will be equalized and reduced to a minimum; to provide improved means for holding the wires in a stretched or taut condition, and permit the stretching devices to be readily detached and replaced in the case of breakage to the parts, and to provide a device of the class named which shall be simple and durable in construction and cheap.

In the accompanying drawings, Figure 1 is a perspective view of my improved fence-post. Fig. 2 is a vertical longitudinal central sectional view on the line a: x of Fig. 1. Fig. 3 is a detached detail view of the winding-pulleys, and Fig. 4 is a view showing three of my improved posts connected by wires that form the fence.

Referring to the drawings, in which like letters of reference denote corresponding parts in the several figures, A designates the base of the fence-post, which is tapered toward its lower end, and has a helical-shaped rib, a, formed on its exterior face, which thus provides a threaded and pointed base, which will readily and freely enter and penetrate the earth and be retained rigidly therein. The upper end of the base has a socket, a, in which is fitted the lower end of a shaft or upright, B, and said shaft is secured in the socket of the base by a tapering key or wedge, b, or by any other preferred means.

G designates a number of sleeves or tubular pieces loosely fitted on the shaft or upright,

and between each adjacent sleeve are arranged two pulleys, D E, to which the fence-wires D E are secured.

Any preferred number of sleeves and pulleys may be employed, the number of pairs of pulleys corresponding in number to the strands of fence-wires D E. The sleeves may be rigidly secured on the shaft, or they may be left free to have vertical and horizontal movements thereon, and the pulleys are free to rotate on the shaft to stretch and tighten the wires D E when it is desired to do so.

Each end of the wire D is secured on or to the pulley D of two adjacent posts, and each end of the wire E is similarly secured to the pulleys E of two adjacent posts. The pulley D of each pair has depending lugs or shoulders f, which enter seats or sockets f in the pulley E, or the position of the partsff may be reversed. Then it is desired to stretch and tighten the wires D E, a wrench of any preferred construction is fitted to the pulleys D E to rotate them simultaneously and in one direction or plane of revolution to draw upon the ends of said wires and wind them around said pulleys, thus effecting the operation of tightening the wires simultaneously.

The periphery of the rollers may be notched to receive a spanner-wrench to tighten the wires, but any preferred implement or tool may be employed for rotating the pulley.

The wire D of each pair of pulleys is secured to the upper flange of the upper pulley, D, and the wire E, that is arranged on the opposite side of the post, is secured to the lower flange of the lower roller, E, whereby the strain or force exerted on the post by the wires D Eis brought to a point approximately common to both, to equalize the force on the post or the shaft B thereof and reduce said strain or force to a minimum.

The upper end of the shaft B is threaded as at g, and on this threaded end works a cap, G, which has an interiorly-threaded socket, g, the function of this cap being to exert press ure on the sleeves and pulleys and prevent rotation or movement thereof when the wires have been stretched.

I do not desire to limit myself to the exact details of construction herein shown and described as an embodiment of my invention,

as I am aware that various changes therein can be made without departing from the principle of my invention.

Having thus fully described my invention, what I claim as new is- V 1. The combination of a post, a pair of coupled pulleys rotatably mounted on the post and adapted to be rotated simultaneously, an independent fence-wire attached to each of the pulleys and extending in opposite direction to adjacent posts, and means for holding the pulleys against rotation after the wires have been stretched, substantially as described.

2. The combination of a fence post, the coupled pulleys mounted thereon and adapted to be simultaneously rotated, independent fence-wires extending in opposite directions and attached to one of the pulleys at points thereon that are arranged close together, and binding-sleeves for preventing the rotation of the pulleys after the wires have been stretched substantially as described.

3. In a fence-post, the combination of a shaft, a series of sleevesmounted on the shaft, and a pair of pulleys arranged between the adjacent ends of two sleeves, and a device for clamping the'pulleys and sleeves rigidly on the shaft, substantially as described.

4. A fence-post comprising a threaded tapered base, a shaft secured in the base, a series of sleeves loosely mounted on the shaft, a pair of connected pulleys arranged between the adjacent ends of two sleeves and having an independent fence-wire secured to each pulley, and a cap for binding the pulleys and sleeves rigidly on the shaft, substantially as described.

In testimony that I I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
